/** The ATK interface provided by UI components which the user can activate/interact with,
 * This should be implemented by instances of Atk::Object classes with which the user can interact directly, i.e. buttons,
 * checkboxes, scrollbars, e.g. components which are not "passive" providers of UI information.
 *
 * Exceptions: when the user interaction is already covered by another appropriate interface such as Atk::EditableText
 * (insert/delete test, etc.) or Atk::Value (set value) then these actions should not be exposed by Atk::Action as well.
 * 
 * Also note that the Atk::Action API is limited in that parameters may not be passed to the object being activated;
 * thus the action must be self-contained and specifiable via only a single "verb". Concrete examples include "press",
 * "release", "click" for buttons, "drag" (meaning initiate drag) and "drop" for drag sources and drop targets, etc.
 * 
 * Though most UI interactions on components should be invocable via keyboard as well as mouse, there will generally be
 * a close mapping between "mouse actions" that are possible on a component and the Atk::Actions. Where mouse and keyboard
 * actions are redundant in effect, Atk::Action should expose only one action rather than exposing redundant actions if
 * possible. By convention we have been using "mouse centric" terminology for Atk::Action names.
